FIGURE 3.3 Two versions of heliostat optical code (HOC) for the cavity receiver and the
cylinder receiver respectively: (A) interface of the specific version of HOC for the DAHAN
solar tower power plant in Beijing with data loaded for all 100 heliostats, (B) arrangement of
2
mirror facets for a 100-m DAHAN heliostat, (C) light path drawing of all DAHAN heliostats
at the solar noon of the spring equinox, (D) simulation of the concentrated solar flux image
on the horizontally north facing target plane by all HAHAN heliostats at the solar noon of
spring equinox, (E) interface of cylinder central receiver solar field layout version of HOC
with field data loaded, (F) simulated solar flux density on the cylinder receiver surface from
all heliostat fields with respect to given parameter settings, and (G) efficient HOC simulation
of the concentrated solar flux map of heliostats on the receiving surface using only a pair of
cross-flux-density profiles to reconstruct a flux density map of the elliptical Gaussian type.
